Visual Studio 2012 Lightswitch Application causes error 'GetAuthenticationInfo'

Cheers! I've a problem with a deployed Visual Studio Light Switch Application. If i start the application out of my visual studio it runs without problems. After i deployed it to our IIS i get the following error: enter image description here

Load operation failed for query 'GetAuthenticationInfo'. Could not load file or assembly 'Microsoft.LightSwitch.Design.Server.Internal, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

I don't really know whats missing. The application has been upgraded from a VS2010 to a VS2012 solution. After i fixed some upcoming build errors after the upgrade the program seems to run without problems in Debug out of Visual Studio.

Also i have running two other Light Switch applications which have been developed in VS2010. Both are running without any problems. Maybe someone knows how to fix this problem? Thanks so far!

Based on Matts reply i used fiddler to encounter the problem (using the trace file gives no information about the problem. Poor tracing ;) )

Fiddler encounters a HTML 404 Error:

<body>
<div id="header"><h1>Server Error</h1></div>
<div id="content">
 <div class="content-container"><fieldset>
  <h2>404 - File or directory not found.</h2>
  <h3>The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.</h3>
 </fieldset></div>
</div>
</body>

Further i found the following information in fiddler:

@Fault5http://schemas.microsoft.com/ws/2005/05/envelope/none@Code@Value�Sender@Reason@Textxmllang�en-US��Could not load file or assembly 'Microsoft.LightSwitch.Design.Server.Internal, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

Seems like something is missing, but i dont know why

I know LightSwitch is being retired, but for anyone still using it who encounters this error, my solution was to install all the IIS components - not just the defaults or minimal set. Hope it helps!
